From: Multiscale analysis of lignocellulose recalcitrance towards OrganoCat pretreatment and fractionation
Structural and compositional changes of OrganoCat extracted lignin compared to untreated material. Semi-quantitative analysis by 2D HSQC-NMR to determine the molar ratio between the observed features. a Monomer composition in lignocellulosic biomass and in the extracted lignin based on NMR analysis. b Lignin linkage distribution in lignocellulosic biomass and in extracted lignin. Values are expressed as mean ± standard deviation; n = 3
